RAILWAY CONSTRUCTION.

Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed January 24 1908. Serial No. 412.428.

To all whom it may concern:

Be it known that I, ABRAHAM L. BUSH, a citizen of the United States, residing at oboken, in the county of Hudson. and State of New Jersey, have invented a new and useful Improvement in Railway Constructions, of which the following is a specifica-. tion.

This invention relates to railway track constructions in which the running or track rails are supported on short supports or blocks which rest on a concrete road bed or foundation.

The object of thisinvention is to produce a track construction in which the rail supports can be easilyremoved and replaced, which is durable and reliable, and avoids undue rigidity.

In the accompanying drawings: Figure 1 is a vertical cross section of the track construction in line 1*1, Fig. 3. Fig. 2 is a top plan view of one of the rail supporting blocks. Fig. 3 is a top planview of the track construction. Fig. tie a longitudinal arranged in the concrete be an outwardly facing of the outer section through the guard rail in line 4 -4, Fig. 3. Fig. 5 is a perspective view of a rail su porting block and filling piece connected y staples.

Like reference characters refer to like parts in the several figures.

represents the rock or earth on which the road is constructed and 11 the concrete bed or foundation laid thereon and reinforced, if necessary, in any suitable manner.

12 represents wooden su porting blocks and projecting above the same so as to support the running or track rails 13 clear of the concrete bath Each block is arranged under one rail only and is 'seatedin a recess or depression in the concretebed, which recess is-closed at its inner end and -opensoutward] The block rests with its inner end against the closed inner end of the recess, whereby the block is held against inward movement. The block is held against outward movement by 7 shoulder or offset 15 formed on one side of the block and bearing against an inwardly facing shoulder 16 in the side of the recess. The shoulder is formed on the block by reducing the width portion of the block and the width of the outer portion of the recess in the concrete bed is correspondingly reduced. he opposite side of the block is straight is engaged by a wedge or filling piece and ' wooden supporting adjacent side of in the recess lengthwise of the rail in enough to disengage itsshoulder 15 i'mnithe shoulder 16 of'the recess, leaving Lh, block free to be removed from under :lie rail through the open outer end of the recess.

The railsare secured to the blocks by any suitable fastening devices, for instanc by tie plates 18 and lag screws or snow spikes '19. I

21 represents wooden guard rails \vhiih extend over the blocks and filling pieces along the outer marginal portions of the concrete bed to which they are secured by anchor bolts 22. The blocks may be connected to the guard rails by lag screws 23 and the wedges or filling pieces can be connected to the guard rails by lag screws hen no 'guard rails are employed the wedges or filling pieces can be secured in position by staples 25 which are driven into adjoining portions of these pieces and the looks, as represented in Fig. 5.

The wedges or filling pieces can be tightened when necessary to take up any looseness arising from shrinkage or wear. When it is necessary to renew a block, the

fastenings of the rail, the block and the wedge are released, the wedge is withdrawn and the block is withdrawn from under the rail. A new block is then inserted under the rail, the wedge is driven home and the fastenings are again applied, as described. This operation can be readily performed by one man and does not in any way interfere with the traflic.

In constructing the track the blocks and wedges can be arranged in the concrete bed in molding the latter. As the tie blocks rest on a solid concrete bed there is no heaving of the track from frost in winter or settlement by lack of drainage. The maintenance in tunnels and subways ofaordinary ballasted track in which the rails rest on cross ties is very expensive and difficult and also dangerous to the track men, and the removal of one of the cross ties requires a gang of men and makes it necessary to protect the traffic while the work is being. done. The

construction are easily removed and replaced,

blocks of the described as stated, and supply sufficient yielding qualities to the track to avoid undue rigidity and are not subject tothe rapid deterioration to which metallic supports are liable in tunnels and subways from engine gases and molsture.

I'Clitllll as my lllVGIliIlOIIf 1. In a railway track construction, the' combination of a concrete bed having a recess transverse to the track, opening outwardly at the side of the bed and provided with a plane bottom, a removable supporting c block provided with a plane bottom an seatedin said recess, means for securing the block in said recess arranged between opposing sides of the recess, and block, and a track rail supported on said block, substan tially as set forth. 1

2. In a railway track construction, the combination of' a concrete bed having a transverse recess which opens outwardly at the side of the bed, a supporting block seated in said recess and movable therein both from side to side of the recess and inwardly and outwardly, securing means for theblock arranged between opposing sides of the recess and block, and a track rail supported on said block, substantially as set forth.

3. In a railway track construction, the

combination of a concrete bed having an a supporting block ,j'

outwardly opening recess, arranged in' said recess, said recess and said,

. outwardly opening an outwg/ blockbeing provided on one side with interlocking shoulders, a removable iilhng piecearran'ged between'the opposite side of 5. In a railway track construction, the.

combination of a concrete bed having an recess provided on one side with an inwardly facing shoulder, 'a

supporting block arranged in said recess and prov'ded on the corresponding side with rdly facing shoulder, a filling piece between the opposite side of said a track rail suparrange recess and sald block. and

ported on said block. substantially as set forth. v
